The lengthy process - further delayed by his scrutineers challenging tens of thousands of votes - ended this afternoon with a victory for the mining magnate.

The official declaration will be held tomorrow.

Mr Palmer tonight hinted that he intends to damage Premier Campbell Newman with claims of corruption after being asked about whether he had evidence of "illegal payments" being made to Queensland ministers.

"Wait for a while, I can't give you all the news tonight, when I get into Parliament we can table, you can read it and you'll love it - Campbell will love it, too," he told ABC TV.

"What I've said is I've got a certain amount of evidence, I don't have conclusive evidence, but it's in the public interest and we'll put it out there in the political debate. Goodbye Campbell Newman."

Mr Palmer now holds the nation's most marginal seat, with a buffer of just 0.03 per cent, making it one of the closest races in Australian political history.

The result comes almost eight weeks after the September 7 federal election, and followed the PUP challenging 50,099 of the 89,176 ballots.

Mr Palmer originally finished ahead of his Liberal National Party challenger Ted O'Brien, but the electoral commission on September 21 automatically ordered a recount because the margin was less than 100 votes.

``I'm looking forward to making a positive contribution to the battle of ideas in Canberra,'' he told AAP.

Queensland's richest man has been an outspoken critic of the Australian Electoral Commission throughout the process, hurling accusations of incompetence.

"How do you manage to lose that many votes and will somebody take responsibility for this fiasco and fall on their sword?" Mr Palmer said in a statement.

"The AEC has just become a joke with some of the mistakes that have been made during the 2013 federal election counting.

"The recount in WA should be declared invalid and the original result restored as it was the only one which has every ballot counted."

Mr Palmer questioned whether the AEC was attempting to "rig" the election.

"We have already seen a number of discrepancies in the counting in my electorate of Fairfax on the Sunshine Coast," he said.

"Is the AEC trying to rig the election? Or are they just completely incompetent?

"Certainly our experience from this election is that there are many issues with Australia's voting system and the AEC needs urgent reform."

Mr Palmer also thanked the 90,000 voters of Fairfax - about half of who voted for him.

"I am thrilled by the result and humbled by the responsibility of representing the people of Fairfax in federal parliament," Mr Palmer said in a statement.

"I'd like to thank Ted O'Brien and all the other candidates. I wish Ted and his family all the best for the future.

"I would also like to thank the AEC staff on the Sunshine Coast who had a very difficult job and had a great deal of pressure on them from the AEC apparatchik from Canberra and Brisbane."

The LNP's Ted O'Brien, who narrowly missed out on holding the Sunshine Coast seat for the party, acknowledged his opponents victory in a statement issued this afternoon.

"I congratulate Clive Palmer on being declared the next Member for Fairfax by the Australian

Electoral Commission," he said.

"It's been a long eight weeks for everyone involved, not least the local community here in

Fairfax that has waited patiently for the count to conclude."

"I would like to thank the hardworking staff of the AEC and also my scrutineers whose

generosity in volunteering their time and expertise has been extraordinary."

Mr O'Brien said the close result was confirmation of the "the old adage that every vote counts"

"But also that every preference counts," he said.

The LNP says it is yet to make a decision about whether it will take the fight to the Court of Disputed Returns.

The party has 40 days to lodge a petition and express doubts about the validity of the result.

LNP State Director Brad Henderson accused Mr Palmer's scrutineers of delaying the count by unnecessarily challenging the authenticity of ballots.

"I note that during the subsequent review of those ballots by the Australian Electoral Officer (AEO), not once did the PUP representatives raise any issues with their authenticity or provide any reason to the AEO for questioning their authenticity," he said.

"Given the sheer scale of this process, in terms of the number and nature of challenges and determinations made, the LNP will now take some time to consider its position."

But Mr Henderson expressed no dissatisfaction with the AEC.

"The LNP takes this opportunity to express its thanks to the AEC and its staff for their hard work and to the people of Fairfax for their patience", he said.

"We also acknowledge the hard work and commitment of our candidate, Ted O'Brien, throughout the campaign.

"Ted has conducted himself with dignity and good grace during what has been an arduous campaign and recount process."
